Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention uses an electromagnetic drive machine as a drive source that moves a mover intermittently back and forth using intermittent electromagnetic force when pulsed power is supplied to an excitation coil, This relates to an electric ball hitting device for a pachinko machine that uses an electromagnetic drive machine to move a ball to hit a ball, and is characterized by being able to set the initial flight distance of a ball to a uniform predetermined distance for each pachinko machine. do.

<Prior Art> As is well known in the past, in an electric ball hitting device for a pachinko machine that moves a firing part by intermittent electromagnetic force generated in an excitation coil, pulsed power from an electrical control device is applied to the excitation coil. Supply power. Therefore, when designing this electrical control device,
A part that is used by assuming in advance the initial flight distance of a batted ball (i.e., the flight distance of a batted ball in the initial state when the player operates the operation unit and turns on the start switch, but does not effectively adjust the flight distance). Define the specifications.

<Problems to be Solved by the Invention> However, there are actually individual differences in capacitors, resistors, etc. used in electrical control devices even if they have the same specifications. For this reason, when an electric control device is connected to an electromagnetic drive machine and installed in a pachinko machine, the initial flight distance of the ball may differ slightly from pachinko machine to pachinko machine.

In addition to the above-mentioned variations in the electrical characteristics of the parts used in the electrical control device, the reasons why this initial flying distance differs from pachinko machine to pachinko machine include the position of the ball delivered to the firing section and the firing position. There are also mechanical variations such as relationship, lateral vibration in the supported state of the projecting part, and individual differences in the electromagnetic drive machine. Therefore, it is difficult to uniformly set the initial flight distance of a batted ball to a predetermined flight distance simply by making the electrical characteristics of each electrical control device uniform.

In any case, if the initial flight distance of the ball varies from pachinko machine to pachinko machine, the player may be forced to shoot the ball involuntarily after starting the game and become accustomed to the particular pachinko machine, causing discomfort. accompanies.

<Means for Solving the Problems> The present invention has been proposed in view of the above, and the movable element (for example, the rotor 5) is intermittently moved by the intermittent electromagnetic force when pulsed power is supplied to the excitation coil 8. This pachinko machine uses an electromagnetic drive machine 1 that moves back and forth as a drive source, and uses this electromagnetic drive machine to move a firing part (for example, the tip of a launch rod 6) to hit a ball at a launch position 31 at the base end of a launch rail 30. In the electric ball hitting device, a pulse generating circuit 47 that generates pulses, a power amplifying circuit 53 that amplifies the pulse output of the pulse generating circuit, and an electric power amount of the initial pulse power of the power amplifying circuit are used as a reference output of elastic force. An electrical control device 44 including at least a reference output setting circuit 54 for adjusting the output voltage is electrically connected to the electromagnetic drive machine,
The present invention is characterized in that the initial flight distance of a batted ball for each pachinko machine can be set to a predetermined distance by adjusting the reference output setting circuit.

<Operation> By changing the resistance value of the variable resistor constituting the reference output setting circuit, the pulse power amount of the power amplifier circuit can be set so that the initial flight distance of the batted ball becomes a predetermined flight distance.

<Example> Hereinafter, an example of the present invention will be described based on the drawings.

The electromagnetic drive machine 1 is a frame-shaped front frame 2 of a pachinko machine.

It consists of a firing section that shoots the ball. And in the illustrated embodiment:
A cylindrical rotor 5 rotatably fitted on the outside of the stator 4 concentrically with the stator 4 is used as a movable element, and a firing rod 6 fixed to the rotor 5 has a spring part. 6' is provided.

The stator 4 is made of a magnetic material such as iron, and the magnetic pole generating portion 7 has an end portion that becomes a magnetic pole located on the outer circumferential side.
Then, the magnetic pole generator 7 is excited to generate an S pole at the end,
It consists of an excitation coil 8 that generates an N-pole magnetic pole, a fixed shaft 9 for fixing these to the mounting board 3, and the like.

According to the illustrated embodiment, the magnetic pole generating section 7 includes a disk-shaped side plate 11 formed at one end of a cylindrical boss 10, and a magnetic pole generating piece slightly shorter than the boss 10 extending from the outer peripheral edge of the side plate 11. 12a, 12b, 12c respectively
A first magnetic pole generating member 13 extending horizontally at three locations at 120 degree intervals and a second magnetic pole generating member 13' having the same configuration as the first magnetic pole generating member 13 are connected to both magnetic pole generating pieces 12a and 12d, 12b, 12e, 12c
The ends 12a' and 12d', 12b' and 12e', and 12c' and 12c are located approximately in the center on the outer periphery.
f' are opposed to each other with a distance l, and a space 14 for accommodating the excitation coil 8 is formed around the bosses 10 and 10'. Note that the end surface of one boss 10' is made convex,
The end surface of the other boss 10 is formed into a concave shape and is fitted. First magnetic pole generating member 13 and second magnetic pole generating member 1
3' can be reliably joined at a predetermined position.

The excitation coil 8 is made by winding a conducting wire, and in the illustrated embodiment, it is wound into a cylindrical shape so that all the magnetic pole generating pieces 12a, 12b, . . . can be excited by a single coil. Insert the bosses 10 and 10' from both openings of the hole 15, and fill the space 1.
Contained within 4. Note that the excitation coil 8 may have any configuration as long as it can excite the magnetic pole generating section 7 by energization, and may be provided for each magnetic pole generating piece 12, or may be provided for each magnetic pole generating piece 12, or for each boss 10, as in the embodiment.
It may be wound along the length of the bosses 10, 10' or radially from the bosses 10, 10'.

In order to fix the excitation coil 8 and the magnetic pole generating section 7 to the mounting board 3, the boss 1 of the magnetic pole generating section 7 is fixed.
A fixed shaft 9 is inserted into the inside of the fixed shaft 9, and an adjustment spacer 17 is attached to a male threaded portion 16 formed at one end of the fixed shaft 9.
Screw together. Then, the tip of the male threaded portion 16 is inserted into the shaft hole 18 of the mounting board 3, and a tightening nut 19 is screwed onto the tip of the male threaded portion 16 protruding from the mounting board 3 to fix it. In addition, in the illustrated embodiment, the fixed shaft 9
Although the magnetic pole generating section 7 is penetrated through the magnetic pole generating section 7, independent shafts may be provided on both sides of the magnetic pole generating section 7, and the magnetic pole generating section 7 may be fixed by these shafts.

The rotor 5 as a movable element that moves along the outer circumferential surface of the stator 4 formed as described above is
A cylindrical rotating body 20 is rotatably provided on the outside of the body so as to enclose the stator 4, and a magnetic adsorption plate is attached to the body of the rotating body 20 at the portion that becomes the magnetic pole of the magnetic pole generating section 7, that is, the outer periphery. These are arranged in correspondence with the end portions which are arranged opposite to each other on the sides. In the illustrated embodiment, the fixed shaft 9 protrudes from both sides of the magnetic pole generating section 7.
Discs 22, 2 having a slightly larger diameter than the magnetic pole generating portion 7
2' are rotatably supported by bearings 23, 23, respectively, and three magnetic adsorption plates 24a, 24b, 24c made of a magnetic material such as iron are arranged at intervals between the outer peripheries of both discs 22, 22'. 3 pairs of ends 12
A' and 12d', 12b' and 12e', and 12c' and 12f' are installed at 120 degree intervals and fixed with screws 25, etc., and the remaining parts are made of non-magnetic material such as synthetic resin. Protective side plates 26a, 26
b, 26c with screws 25 etc., and stator 4
A cylindrical rotating body 20 that includes the stator 4 and rotates concentrically with the stator 4 is configured.

Further, an engaging piece 27 projecting outward is integrally formed at the end of one of the protective side plates, for example 26a, on the side of the mounting plate 3, and the entire body is L-shaped. is used as a regulating member for the rotation angle of the rotator 5, and the horizontal portion is used as a protective side plate. Note that the engaging pieces 27 may be formed separately from the protective side plates 26 and fixed to the protective side plates 26 or the disc 22.

In addition, in FIG. 2, 28 is an arc-shaped long hole opened in the disk 22, and is used to pass the conducting wire 8' of the excitation coil 8 passed through the conducting wire take-out hole 29 opened in the magnetic pole generating section 7. The hole has an appropriate length that does not cause any problem even when the rotator 5 rotates. Instead of opening this elongated hole 28, a notch may be provided.

The firing rod 6 that shoots the ball has a resilient part 6' made of an elastic body that directly collides with the ball at its upper end. It is configured to rotate integrally with the mover 5.

In the illustrated embodiment, the base end of the firing rod 6 is fixed to the disk 22 on the mounting board 3 side with a screw 25', but it is formed integrally with one of the magnetic adsorption plates, for example 24a, so that the entire structure is It may be L-shaped, with the vertical part of the L-shape serving as the firing rod 6 and the horizontal part serving as the suction plate 24a. By integrally molding the suction plate 24 in this way, both can be attached and detached in one operation. That is, by screwing the left and right ends of the suction plate 24 to the discs 22, 22', the firing rod 6 can be firmly fixed.

Since the firing rod 6 in this embodiment is fixed to the cylindrical rotating body 20 in this manner, the length can be made shorter than that fixed to the output shaft of a conventional rotary solenoid. Therefore, lateral vibration during rotation can be extremely reduced, and defective firing such as uneven skipping caused by lateral vibration can be eliminated. In addition, the force of the rotator 5 as a mover can be efficiently applied to the springing part 6' of the firing rod 6, so in other words, the point of force can be brought closer to the springing part 6', which is the point of application. Therefore, due to the principle of leverage, even with the same magnetic force, a stronger repulsive force can be obtained compared to a conventional rotary solenoid that rotates at the center.

To attach the electromagnetic drive machine 1 constructed as described above to a pachinko machine, as shown in FIG.
Face the mounting board 3 at a predetermined position on the back side of the front frame 2 so that the projecting portion 6' of the projector enters the firing position 31 at the base end of the firing rail 30 attached to the game board, and fix it with screws 25'', etc. To adjust so that the resilient part 6' of the firing rod 6 enters the center of the firing position 31, use the adjustment spacer 17 and nut 19 of the fixed shaft 6.
is rotated appropriately to change the distance between the mounting board 3 and the rotator 5, and adjust the position of the firing rod 6.

In order to regulate the rotation angle of the firing rod 6, the mounting board 3 is provided with a fixed stopper 32 in front of the firing rod 6, and a fixed stopper 32 is provided at the rear in conjunction with the ball hitting operation part 33 on the front of the pachinko machine to stop the firing rod 6. A variable stopper 34 for adjusting the position is provided. Fixed stopper 3
2 is made of a cushioning material such as rubber, and is arranged so as to come into contact with the firing rod 6 when it rotates to the ball firing position (dotted chain line in FIG. 4). On the other hand, the ball hitting operation section 3
3 is a front gripping member 35 as shown in FIG.
and a rear gripping member 37 having a cylindrical holding portion 36.
An operating lever 38 is rotatably provided between the mounting board 3 and the operating lever 38 is biased counterclockwise by a spring 39. Screw 4 from behind 3
It is fixed by 0... Then, the shaft of the operating lever 38 is penetrated through the inside of the rear gripping member 37 and protrudes from the back side of the mounting board 3, and the variable stopper 34 is fixed to the tip of the shaft 41. The variable stopper 34 shown in FIGS. 4 and 5 is a spiral cam whose distance from the shaft 41 gradually increases. Consisting of When the operating lever 38 is not rotated (solid line in Figure 4), the engagement piece 27 contacts the cam circumferential surface furthest from the shaft 41, and the operating lever 38 is rotated clockwise. As it moves forward, it comes into contact with the cam peripheral surface at a small distance from the shaft 41 (broken line in Figure 4). That is, the firing preparation position where the firing rod 6 comes into contact with the variable stopper 34 and stops moves backward in accordance with the amount of rotation of the operating lever 38. Therefore, the rotation angle of the firing rod 6 increases according to the amount of rotation of the operating lever 38. If the rotation angle is large, the acceleration time of the firing rod 6 becomes longer, so the rotational speed of the firing rod 6 increases, thereby increasing the firing force of the batted ball and extending the flight distance of the batted ball.

In order for the firing rod 6 to reciprocate between the firing preparation position and the batting ball firing position, when the firing rod 6 is stationary at the batting ball firing position, the end of the magnetic pole generating portion 7 of the stator 4 is 12a', 12b'... and the center lines of the adsorption plates 24a, 24b, 24c provided correspondingly are arranged on the radial line from the fixed shaft 9 in advance. 24a, 24
Adjust the positions of b and 24c. Further, at the firing position, the firing rod 6 is stopped with a slight backward inclination. Note that when the firing rod 6 is stationary at the firing preparation position, it is desirable that the end of the magnetic pole generating section 7 and the suction plate partially overlap.

Next, the operation will be explained. When a player operates the ball-striking operation unit 33 provided at the lower right side of the pachinko machine, pulsed power of a constant width is supplied to the excitation coil 8 connected via a lead wire from an electric control device (described later), and the excitation coil 8 is excited. As a result, the magnetic pole generating section 7 is magnetized, and each end 12a', 1 of each magnetic pole generating piece 12a, 12b, 12c...
Magnetic poles are generated at 2b', 12c', . . . , respectively. for example,
If the adjustment spacer 17 side of the stator 4 is the N pole,
The other end becomes the S pole, and the magnetic flux coming out from the N pole is transmitted to the ends 12a', 12 of the magnetic pole generating pieces 12a, 12b, 12c.
b', 12c' are respectively formed with N poles, and the ends 12d', 12f of the other magnetic pole generating pieces 12d, 12e, 12f are formed.
S poles are formed at e' and 12f', respectively. Therefore,
End 12a' (N pole) and end 1 of the magnetic pole generating piece 12a
A strong magnetic field is generated between 2d' (south pole), 12b' (north pole) and 12e' (south pole), and between 12c' (north pole) and 12f' (south pole), respectively. suction plate 24a,
24b and 24c are instantly attracted. The rotating element 5 rotates due to the attractive force of the magnetic force, and the firing rod 6 rapidly rotates from the firing preparation position to the ball hitting position to hit the ball at the firing position 31.

When the firing rod 6 rotates to the ball firing position, the pulse power supply to the excitation coil 8 disappears, and the excitation coil 8
is demagnetized, so each magnetic pole generating piece 12a, 12b...
The magnetic fields at the ends 12a', 12b'... disappear. Therefore, the firing rod 6 rotates back due to the reaction of the bullet and its own weight, and returns to the firing preparation position. In addition, in order to ensure that the firing rod 6 returns to its original position and to make the next shot stable, a weak spring or the like is used to hold the firing rod 6.
may be slightly biased toward the firing preparation position.

Then, when the next pulse is supplied to the exciting coil 8, the magnetic pole generator 7 is excited again. Thereafter, by repeating this process, balls are fired intermittently.

In the present invention, the ball is hit as described above, but in order to start or end the ball hitting motion or adjust the firing force, the ball hitting operation section 33 provided on the front of the pachinko machine is operated. Let's do it.

Rear handshake member 3 constituting the ball hitting operation section 33
A micro switch 42 is provided inside the switch 7 as a switch function part, and a pressing piece 43 protruding from the back side of the operating lever 38 is made to face the operating protrusion of the micro switch 42. This microswitch 42 is always in an open state (OFF) because the pressing piece 43 presses the operating protrusion under the bias of the spring 39. When the player turns the operating lever 38 clockwise against the bias of the spring 39, the pressing piece 43 separates from the operating protrusion, and the micro switch 42 changes from the open state (OFF) to the closed state (ON). ) and sends a start command to the electrical control device 44 via the lead wire.

Note that the switch function section is not limited to the micro switch 42 described above, and may have any configuration as long as it switches (ON-OFF) in conjunction with when the player operates the batting operation section 33. good. For example, the surface of the front handshake member 35 is plated with chrome to make it conductive, the lead wire 45 is wired to the front handshake member 35, and the lead wire 43
is connected to the touch detection circuit 46, and when the player touches the front handshake member 35 of the ball batting operation section 33, the touch detection circuit 46 is switched on and turned ON.
An activation command may be sent to the electrical control device 44.

The electrical control device 44, as shown in FIG.
A switch function section, for example, the above-mentioned micro switch 4
The pulse generating circuit 47 has a pulse generating circuit 47 triggered by the pulse number 2, whose pulse repetition frequency can be adjusted by a pulse number variable section 48, and its pulse width can be set by a pulse width setting device 49.
Semiconductor chips for such pulse generators are already known, and can be obtained, for example, by constructing a timer using NE556 and adjusting its CR time constant using a variable resistor. 50 via plug 51
It is a rectifier bridge connected to a 24 volt AC power supply, and 52 indicates a smoothing circuit capacitor. One conductor of the excitation coil 8 is connected to this rectifying and smoothing circuit, and the other conductor is connected to a power amplification circuit 53 consisting of Darlington-connected transistors.
and a reference output setting circuit 54 formed by connecting a resistor R ₁ and variable resistors R ₂ and R ₃ in parallel to ground. Note that 55 is a freehold diode.

The base of the transistor constituting the power amplification circuit 53 is connected to the output terminal of the pulse generation circuit 47.

Therefore, when the player turns the operating lever 38 of the ball-hitting operation unit 33 to close the micro-switch 42 (ON), the pulse generating circuit 47 that receives the activation command from the micro-switch 42 starts. . Note that when the touch detection circuit 46 is provided, the player can touch the front handshake member 35 of the ball-hitting operation section 33.
When touched, the touch detection circuit 46 closes and starts the pulse generation circuit 47.

When the pulse generation circuit 47 starts, a pulse having a repetition frequency and pulse width determined by the pulse variable section 48 and the pulse width setting device 49 is generated.
The signal is input to the power amplifier circuit 53. Therefore, when the operating lever 38 is rotated, the transistor of the power amplification circuit 53 operates, and the excitation coil 8 can be powered with a corresponding current pulse. Therefore, the excitation coil 8 intermittently excites the magnetic pole generator 7, and rapidly rotates the firing rod 6 each time it is excited.

It is desirable for the flight distance of the ball to be stable. However, in general, the current flowing through the transistor increases as the temperature rises, and the power supplied to the excitation coil 8 changes. In order to compensate for this change, in this embodiment, an appropriate number of semiconductor diodes connected in series are inserted in the forward direction between the pulse generation circuit 47 and the power amplifier circuit 54. This is because the internal resistance of a semiconductor diode generally increases as the temperature rises, which acts to suppress the input current to the next stage transistor circuit. It is clear that fluctuations in the pulse current or voltage applied to the excitation coil 8, or both, affect the flight distance of the ball, and the diodes 56 comprehensively compensate for these fluctuations. Therefore, the circuit portion formed by the diodes 56 functions as a constant power stabilizing circuit.
Note that this constant power stabilizing circuit may have any configuration as long as it can compensate for fluctuations in the current and voltage of pulses applied to the excitation coil 8, and in addition to the above-mentioned diode, it may also include a thermistor with positive characteristics, etc. It may also be configured by

Furthermore, even if the electrical control device 44 has the same circuit configuration, the capacitors, resistors, and
Since there are individual differences in transistors, etc., the standards for the power supplied to the excitation coil 8 are slightly different. For this reason,
When installed in a pachinko machine and connected to the electromagnetic drive unit 1, the initial ball flight distance by the pachinko machine, that is, the distance of the ball fired without adjusting the ball launch force, can be determined by simply turning on the micro switch 42. Somewhat different. Therefore, as shown in FIG. 7, a driver 59 or the like is inserted into the adjustment hole 58 formed in the protective case 57 of the electrical control device 44, and the resistance values of the variable resistors R ₂ and R ₃ of the reference output setting circuit 54 are adjusted. Adjust. Note that since the reference output setting circuit 44 has a plurality of variable resistors connected in parallel, it can be finely adjusted over a wide range. This allows the initial ball flight distance of all pachinko machines to be adjusted to a uniform predetermined distance in assembly plants and game parlors.

As mentioned above, by changing the resistance values of the variable resistors R ₂ and R ₃ , the strength of the pulse power of the power amplifier circuit 53 changes, and the excitation force of the excitation coil 8 can be finely adjusted. The initial flying distance can be set to a predetermined distance.

Note that the variable resistor R ₂ of the reference output setting circuit 54,
When adjusting _R3 , there are mechanical variations such as the positional relationship between the firing rod 6 and the ball and individual differences in the electromagnetic drive machine 1, so make fine adjustments for each pachinko machine while actually firing the ball. Set to a predetermined initial flight distance. The initial flight distance of the ball depends on the structure of the pachinko machine, but as shown in FIG. any distance within a range that is not
Set the distance beyond 20cm.

According to the pachinko machine in which the initial flight distance of the batted ball is set as described above, the player adjusts the batted ball to exceed the above-mentioned initial flight distance and fires the ball by operating the batting ball operation section 33, and then shoots the ball by operating the batting ball operation section 33. It is possible to hit a desired position within the enclosed gaming section 62.
Then, this hit ball flows down while hitting an obstacle nail (not shown), and enters the winning hole 63 on the way.
Alternatively, it directly enters the out port 64. In addition, when playing such a game, players are encouraged to try out a trial shot, since the initial flying distance for each pachinko machine is set to a predetermined flying distance, regardless of which pachinko machine the player is playing on. There's no need to do it. Furthermore, when the player moves to another pachinko machine or stops playing, the flight distance of the ball is adjusted to a distance that does not exceed the upper end 61' of the inner guide rail 61.
The balls remaining inside the ball supply mechanism 65 can be returned to the receiving tray 66 from the Farr ball opening 60 as Farr balls.

In the above embodiment, the rotation angle of the firing rod 6 is adjusted by the variable stopper 34, but as shown in FIG. The pulse output of the pulse generation circuit 47 may be adjusted by the resistor 67, and the power amplification circuit 53 may supply pulsed power to the excitation coil 8 in response to this pulse output (FIG. 10). In this case, fixed stoppers 32a and 32b are installed on the mounting board 3 so that the firing rod 6 can reciprocate within the distance between the stoppers 32a and 32b. In this way, when the variable resistor 67 is provided in the ball-hitting operation unit 33 and the player adjusts the flight distance using the variable resistor 67, when setting the initial flight distance of the ball, the micro switch 42 Just by turning on the variable resistor 67
The reference output setting circuit 54 is not operated effectively.
Adjust the variable resistors R ₂ and R ₃ .

Note that the electromagnetic drive machine 1 according to the present invention is not limited to one in which a rotor 5 as a mover is rotatably fitted on the outside of a stator 4, but can be rotated by intermittent electromagnetic force of pulsed power supply. Any configuration may be used as long as the mover is moved back and forth intermittently.
For example, it may be a known rotary solenoid in which a rotor is rotatably provided inside a cylindrical stator, or it may be a plunger type solenoid in which a plunger moves back and forth linearly within a magnetic field.

<Effects of the Invention> As explained above, according to the present invention, the drive source is an electromagnetic drive machine that moves the mover back and forth intermittently by the intermittent electromagnetic force when pulsed power is supplied to the excitation coil, and the electromagnetic drive In an electric ball hitting device for a pachinko machine that uses a driving machine to move a firing part and hit a ball at a firing position at the base end of a firing rail, a pulse generating circuit that generates pulses and amplifying the pulse output of the pulse generating circuit are provided. An electrical control device that includes at least a power amplification circuit and a reference output setting circuit that electrically adjusts the elastic force of the initial pulse power amount of the power amplification circuit as a reference output is electrically connected to the electromagnetic drive machine. Therefore, it is possible to adjust the amount of pulse power supplied from the power amplifier circuit to the excitation coil in each pachinko machine to accurately adjust the initial flight distance of the ball to a predetermined distance. Therefore,
In an assembly factory or a pachinko parlor, it is possible to equalize the initial flying distance of each pachinko machine. Therefore, players can adjust the flight distance of the ball with the same feeling no matter which pachinko machine they are playing on, and they can also adjust the flight distance of the ball from the start of the game without wasting balls on trial shots. You can immediately hit the ball into the spot.
